Passage Two

听力原文

    (19) Today I found out that Seattle doesn’t really get that much rain compared with most US cities. In fact, Seattle ranks 44th among major US cities in average annual rainfall. Cities that get more rainfall than Seattle include Huston, Memphis, Nashville, and pretty much every major city on the eastern coast, such as New York, Boston, and Miami. So, why does everyone think of Seattle as a rainy city? The primary root of this misconception lies in that Seattle has a relatively large number of days per year with rainfall, compared with New York and Boston, which get an average of about 16% more rain per year than Seattle, but also average between them about 36 fewer days a year of rainfall. So it rains a lot less in Seattle. And the rain is spread out over more days than those cities. (20) This is why few locals in Seattle carry an umbrella generally. When it does rain, it tends to be a very light rain that isn’t troublesome. It almost never really rains as most people think. On top of that, it never really storms in Seattle, either. Seattle gets an average of a mere 7 days a year with thunder. (21) So in short, if you like sunny but not too hot summers, mild winters but with lots of cloudy days, Seattle’s the place to be. Anyway, if you visit Seattle, don’t bring an umbrella. People will look at you, thinking you are funny.

21. Why does the speaker say Seattle is a good place to be? 

解析：D。录音末尾部分提到，如果你喜欢晴朗但又不那么热的夏天（summer）、温和（mild）而多云的冬天（winter），西雅图是个合适的地方，故正确答案为D。A项的关键词places for entertainment在录音中并未提及，故排除。B项的thunder在录音的后半部分提到过，但原文说的是，西雅图从来没有过真正的暴风雨，那里平均每年只有7天会打雷，并不等于从未出现过雷电，故B项错误。录音中间部分提到，西雅图降雨的天数要比另一些城市更多，由此可推断，西雅图阴天的时候应该也很多，而在录音末尾又说到西雅图的冬季阴天也很多，故C项内容与录音文意不符，可排除。
